QMA M RA CRIMP for RG58/RG142/LMR195/LMR200 Cable

Description

The QMA series is a quick-disconnect evolution of the SMA interface, specifically designed to enhance assembly speed and port density in modern wireless systems. This male (plug) variant features a 90-degree right-angle configuration, which is essential for optimizing cable management in shallow equipment racks and high-density panels. The right-angle orientation allows the cable to exit parallel to the equipment faceplate, significantly reducing mechanical stress and protecting the cable’s minimum bend radius in tight enclosures.

Specifically calibrated for the 5mm (0.195″) cable class—including the flexible RG58, high-performance RG142, and low-loss LMR195/LMR200—this connector maintains a strict 50-Ohm impedance. It utilizes a professional dual-crimp termination system for both the center pin and the outer ferrule, ensuring a gas-tight mechanical bond. The QMA’s signature snap-on coupling mechanism allows for tool-free installation and 360-degree rotation after mating, which eliminates the risk of torque-related damage to the cable or the interface during deployment.

Key Technical Advantages

• Space-Saving 90° Integration: The low-profile right-angle body minimizes protrusion from the equipment panel, making it ideal for high-density layouts where rack depth is limited.

• Rapid Snap-On Efficiency: The tool-free “Quick-Lock” mechanism reduces installation time by up to 10 times compared to threaded SMA connectors, facilitating faster site builds and maintenance.

• 360° Rotational Stress Relief: Once mated, the connector can rotate freely, allowing for easier cable routing and preventing damaging torque from being transmitted to the connector internal components.

• 5mm Cable Precision Matching: Specifically engineered for RG58, RG142, and LMR195/200 series cables, ensuring an optimized electrical transition and minimal return loss up to 6 GHz.

• Superior Environmental Durability: Manufactured with a gold or nickel-plated brass body and premium PTFE insulation for long-term reliability in professional networking environments.
